Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal tendons
- Rich in collagen, which softens over long gentle simmering into gelatin for a silky texture.
- Onions
- Browning in butter develops sweetness and deeper savory flavor in the finished dish.
- Butter
- Adds fat for browning the onions and enriching the sauce base.
- Broth or water
- Forms the liquid that the roux thickens and the tendons simmer in.
The step that matters
Simmering the tendons on low heat. Veal tendons are full of collagen that needs slow, gentle heat over time to break down into gelatin. Boiling or rushing toughens the meat and leaves the texture chewy rather than tender.
